Adsorption of Reactive Red 195 from polluted water upon Na2CO3 Modified Jute Fibre.

Abstract

Sorption of Reactive Red 195 upon Na2CO3 modified Jute Fibre was studied for different concentrations of dye solutions (50, 100, 150 and 200 mg/L). Experiments were done considering parameters such as agitation time range, solution pH (4-12), adsorbent dose (10 gm/L-20 gm/L) and temperature (293, 303 and 313 K). The adsorption was highly supported at pH 6-7 and lower temperatures. Adsorption phenomena is better explained by Langmuir isotherm, the process of adsorption was best described by the second order pseudo-kinetic model. The maximum sorption ability (qmax) is found to be 22.47 mg/g. it was suggested that adsorption is atypical chemical process, exothermic and spontaneous, and in nature, the equilibrium sorption occurred at pH 7.0,. Absorption effects was studied and optimum adsorption was obtained at a jute dose of 15gm/L Keywords-Na 2 CO 3 Modified Jute Fibre (NaMJF), Reactive Red 195, Isotherm.
